FIELD OF THE DISCLOSURE

The present disclosure relates to medical devices and, more particularly, to a navel retainer for use in combatting navel contracture.

BACKGROUND

In placental mammals, the umbilicus, also known as the navel or belly button, is the attachment site of the umbilical cord. Navel size and shape vary from species to species and even between individual mammals of a given species. In humans, the navel normally resides on the abdomen and is generally rounded in shape. Colloquially, navels of generally concave indentation are known as “innies,” whereas navels that protrude beyond the abdomen are known as “outies.”

DETAILED DESCRIPTION

A navel retainer and related techniques are disclosed. In accordance with some embodiments, the disclosed navel retainer may be configured to be deployed within a navel such that its body portion interfaces, directly or indirectly, with tissue therein. In some embodiments, the disclosed navel retainer may be configured as an adjustable element, including an adjustment mechanism configured to expand and collapse the size and, optionally, geometry of the body portion. In some embodiments, the disclosed navel retainer may be configured as a resilient element, characterizable as tending to recoil or spring back into shape despite being compressed or otherwise deflected from an undisturbed state, allowing it to be temporarily compressed and subsequently allowed to expand in size, in some cases also optionally changing its geometry. In either manner, the disclosed navel retainer may be adjusted in size and/or geometry to buttress the tissue of the navel, minimizing or otherwise reducing opportunity for contracture of the navel, for example, during the healing process. In accordance with some embodiments, after a desired navel size and shape are achieved, a separate maintenance device optionally may be deployed within the navel. In some embodiments, the disclosed navel retainer may be configured to host or otherwise serve as a navel adornment. Numerous configurations and variations will be apparent in light of this disclosure.

General Overview

Contracture of the navel may result from surgeries, pregnancy, or localized injury, among other sources. In some instances, the contracture is severe enough to cause deformity of the navel. Existing approaches to combating physiological forces involved in navel contracture include insertion and retention of a marble or a foam earplug in the navel during the healing process. However, such existing approaches are not normally permanently effective, can be undesirably noticeable under clothing or with an exposed midriff, and can lead to additional medical complications, including infection, as well as pain.

Regarding navel piercings, not every individual's anatomy may be conducive to piercing. Without a well-defined region of tissue at the navel, there is an increased chance for difficulties during the healing process after piercing, including rejection by the body. Because the tissue in the navel region may not be particularly vascular, the lesser blood flow to the area may extend the healing process. Moreover, because of its location, navel piercing sites typically are subjected to constant bending, stretching, folding, and friction, each of which can contribute to extending the healing process. Additional complications related to navel piercings may include scarring, tearing, and pain, as well as infection and blood poisoning in some cases. With the long healing time and commitment required in maintaining sanitary conditions of the piercing site, navel piercing may be a decision worthy of careful forethought.

Thus, and in accordance with some embodiments of the present disclosure, a navel retainer and related techniques are disclosed. In accordance with some embodiments, the disclosed navel retainer may be configured to be deployed within a navel such that its body portion interfaces, directly or indirectly, with tissue therein. In some embodiments, the disclosed navel retainer may be configured as an adjustable element, including an adjustment mechanism configured to expand and collapse the size and, optionally, geometry of the body portion. In some embodiments, the disclosed navel retainer may be configured as a resilient element, characterizable as tending to recoil or spring back into shape despite being compressed or otherwise deflected from an undisturbed state, allowing it to be temporarily compressed and subsequently allowed to expand in size, in some cases also optionally changing its geometry. In either manner, the disclosed navel retainer may be adjusted in size and/or geometry to buttress the tissue of the navel, minimizing or otherwise reducing opportunity for contracture of the navel, for example, during the healing process. In accordance with some embodiments, after a desired navel size and shape are achieved, a separate maintenance device optionally may be deployed within the navel. In some embodiments, the disclosed navel retainer may be configured to host or otherwise serve as a navel adornment.

In accordance with some embodiments, the disclosed navel retainer may be considered, in a general sense, a medical device configured to help keep the navel open at normal (or otherwise desired) dimensions and geometry during (and optionally after) healing of the navel and surrounding region of the abdomen. In at least some cases, the disclosed navel retainer may be utilized, for example, in post-operative care after abdominal surgery (e.g., umbilical hernia repair surgery; abdominoplasty or “tummy tuck” surgery) or during healing in the post-natal period or following a localized abdominal injury, among other scenarios. Use of the disclosed navel retainer may serve to minimize or otherwise reduce the opportunity for navel deformity to occur during such healing periods. In accordance with some embodiments, the disclosed navel retainer may be configured to provide for adjustment and progression of the size and, optionally, shape of the device, and thus the host navel, without need for using a series of individual umbilical splints of different sizes and shapes. Moreover, use of the disclosed navel retainer may be a safe and practical alternative to traditional navel piercings for users of all ages, eliminating or otherwise reducing complications normally associated therewith.

As will be appreciated in light of this disclosure, the disclosed navel retainer may be used periodically or continuously for a given period. As will be further appreciated, the adjustable nature of the disclosed navel retainer may make it ideal for use in cases of protracted healing periods and for customizable umbilicus shaping and sizing. The disclosed navel retainer also may be configured for use in conjunction with, or on its own as, navel jewelry. As will be further appreciated, the disclosed navel retainer may be configured, in accordance with some embodiments, so as not to require any bandage, wrap, tape, adhesive, or other further external element to effectuate deployment and retention in the navel. More generally, the disclosed navel retainer may be configured for deployment and retention with any umbilicus, whether protruding (e.g., an “outie”) or recessed (e.g., an “innie”).

Structure and Operation

FIGS. 1-2 illustrate several views of a navel retainer 100 a configured in accordance with an embodiment of the present disclosure. FIGS. 3-4 illustrate several views of a navel retainer 100 b configured in accordance with another embodiment of the present disclosure.

As can be seen, navel retainer 100 a, 100 b may include a body portion 101, which may be configured to interface, directly or indirectly, with the interior sidewalls of a navel. In some embodiments, such as that generally shown in FIGS. 1-2, body portion 101 may be of multi-piece construction (e.g., may constitute a polylithic element), including a first body portion 102 and a second body portion 104, which may be disposed substantially opposite one another. In some other embodiments, such as that generally shown in FIGS. 3-4, body portion 101 may be of single-piece construction (e.g., may constitute a monolithic element). Depending on the orientation of navel retainer 100 a, 100 b when inserted within a navel, a given region of body portion 101 may be considered, for example, an upper body portion, lower body portion, or side body portion of navel retainer 100 a, 100 b, as the case may be. In some embodiments, a given region of body portion 101 optionally may be configured to host one or more intervening layers (e.g., coatings, bumpers, guides, sleeves, coverings, guards, etc.) which are to be disposed between the tissue of the navel and body portion 101. The material selection and dimensions of such optional intervening layer(s) may be customized, as desired for a given target application or end-use.

The dimensions and geometry of body portion 101 may be customized, as desired for a given target application or end-use. In accordance with some embodiments, a given body portion 102, 104 may be of generally rounded shape. For instance, a given body portion 102, 104 may be arcuate (e.g., semi-circular, semi-elliptical, open curve) or otherwise curved in shape and may have a substantially constant radius or a variable radius, as desired for a given target application or end-use. In some embodiments, navel retainer 100 a may be configured such that, in its fully collapsed state, body portions 102, 104 interface in a manner that results in body portion 101 being of generally circular geometry. In some other embodiments, navel retainer 100 a may be configured such that, in its fully collapsed state, body portions 102, 104 interface in a manner that results in body portion 101 being of generally elliptical, oval, oblate, prolate, or other curved geometry suitable to fit within a navel of a given size. In accordance with some embodiments, navel retainer 100 a, 100 b may be configured such that, in its fully collapsed state, its body portion 101 may be of a first geometry (e.g., a circular geometry), whereas in a partially or fully expanded state, its body portion 101 may be of a different second geometry (e.g., an elliptical geometry). As will be appreciated in light of this disclosure, in cases where body portion 101 is of single-piece construction, it may be of any of the various example geometries discussed above, for instance, with respect to a body portion 101 of multi-piece construction. Other suitable configurations for body portion 101 (e.g., with its one or more constituent body portions) will depend on a given application and will be apparent in light of this disclosure.

Navel retainer 100 a also may include one or more brace portions 106, 108, which may be configured, in accordance with some embodiments, to provide a given degree of structural rigidity to navel retainer 100 a and serve to operatively couple a given body portion 102, 104 with adjustment mechanism 112 (discussed below). In some embodiments, a given brace portion 106, 108 and its corresponding body portion 102, 104 may be of single-piece construction (e.g., may constitute a monolithic element), whereas in some other embodiments, they may be of multi-piece construction and assembled with one another (e.g., may constitute a polylithic element). The dimensions and geometry of a given brace portion 106, 108 may be customized, as desired for a given target application or end-use. In some cases, a given brace portion 106, 108 may be a substantially elongate, bar-like body, extending from a center portion 110 (discussed below) to a corresponding given body portion 102, 104. In some instances, a given brace portion 106, 108 may be of generally constant width along its length, whereas in some other instances, its width may vary along its length. For instance, as generally can be seen from FIG. 1, in some embodiments, a given brace portion 106, 108 may be of greater width (e.g., flared) at its distal end, which interfaces, directly or indirectly, with a corresponding body portion 102, 104, than at its proximal end, which interfaces, directly or indirectly, with center portion 110. Other suitable configurations for brace portions 106, 108 will depend on a given application and will be apparent in light of this disclosure.

As previously noted, navel retainer 100 a may include a center portion 110, which may be disposed in a generally centered manner with respect to one or more axes of navel retainer 100 a. In some cases, center portion 110 may be disposed substantially equidistantly from body portions 102, 104, though in some other cases, center portion 110 optionally may be disposed closer to one of body portions 102, 104 than the other. The geometry and dimensions of center portion 110 may be customized, as desired for a given target application or end-use. As discussed below, an adjustment mechanism 112 of navel retainer 100 a may be disposed, in part or in whole, at center portion 110, in accordance with some embodiments. Other suitable configurations for center portion 110 will depend on a given application and will be apparent in light of this disclosure.

As previously noted, navel retainer 100 a may include an adjustment mechanism 112 configured to provide for expansion and collapsing of the size (and, optionally, change in geometry) of body portion 101 along one or more axes. More specifically, adjustment mechanism 112 may be configured, in accordance with some embodiments, to advance and retract either (or both) brace portions 106, 108 and their attendant body portions 102, 104 in a linear or other desired manner with respect to center portion 110 (or other specified portion of navel retainer 100 a). To such ends, adjustment mechanism 112 may be configured to generate movement in one or more directions based on mechanical, hydraulic, pneumatic, electronic, magnetic, or any other suitable force application means. For instance, in accordance with some embodiments, adjustment mechanism 112 may be any one, or combination, of a threaded screw-based mechanism, a spring-based mechanism, or a gear-based mechanism, among others.

In some embodiments, adjustment mechanism 112 may be configured to operate such that body portion 101 of navel retainer 100 a may increase or decrease in size, as the case may be, in a smooth incremental manner. In some other embodiments, however, adjustment mechanism 112 may be configured to operate such that body portion 101 of navel retainer 100 a may increase or decrease in size, as the case may be, in a stepwise or other non-smooth incremental manner. For instance, in an example case, adjustment mechanism 112 may be configured for ratchet-type adjustment, having one or more defined stopping points, the quantity and pitch of which may be customized, as desired for a given target application or end-use. In some embodiments, adjustment mechanism 112 may be configured to provide continuous adjustment of the size of body portion 101, whereas in some other embodiments, adjustment mechanism 112 may be configured to provide discontinuous adjustment of the size of body portion 101. Adjustment may be provided via any one, or combination, of manual or automated means, such as, for example, by hand, by tool, or by external device. Other suitable configurations for adjustment mechanism 112 will depend on a given application and will be apparent in light of this disclosure.

In at least some cases where body portion 101 is of multi-piece construction, its constituent body portions 102, 104 may be physically separated from one another by a gap 114. Similarly, in at least some cases where body portion 101 is of single-piece construction, body portion 101 may be discontinuous, being separated by a gap 114. As will be appreciated in light of this disclosure, the dimensions of a given gap 114 may change, for instance, depending on whether navel retainer 100 a, 100 b is in its fully collapsed state, fully expanded state, or some intermediate expanded state there between. In accordance with some embodiments, as adjustment mechanism 112 is operated to effectuate adjustment of the size (and, optionally, geometry) of navel retainer 100 a, a given gap 114 may increase or decrease in size accordingly. As a given gap 114 approaches zero, body portions 102, 104 may come to interface, directly or indirectly, with one another. Other suitable configurations for gap(s) 114 will depend on a given application and will be apparent in light of this disclosure.

In accordance with some embodiments, navel retainer 100 a, 100 b optionally may include one or more biasing members 116, which may be disposed, in part or in whole, within a given gap 114, for instance, between body portions 102, 104. A given biasing member 116 may be configured, in accordance with some embodiments, to help maintain a given desired orientation and/or spacing between body portions 102, 104. In some embodiments, a given optional biasing member 116 may be a collapsible or extendable body configured to compress or stretch with the movement of body portions 102, 104 relative to one another. For example, a given biasing member 116 may be, in some cases, a spring, an elastomeric element, a piston, or a body capable of telescoping, to name a few. In some other embodiments, a given optional biasing member 116 may be a rigid (or semi-rigid) body that, rather than collapsing or extending, is configured to be hosted, in part or in whole, by a corresponding recess in either (or both) body portions 102, 104. To that end, a given biasing member 116 may be, for instance, a rod-type body of solid or hollow (e.g., tubular) configuration, and a corresponding recess may be provisioned such that the rod-type body may be inserted into and withdrawn from it with the movement of body portions 102, 104 relative to one another. Optionally, such a rod-type body and corresponding recess may be configured for threaded screw-like engagement, in accordance with some embodiments. Other suitable configurations for optional biasing member(s) 116 will depend on a given application and will be apparent in light of this disclosure.

In accordance with some embodiments, navel retainer 100 a, 100 b optionally may include one or more points of attachment for ornamentation, such as navel piercing jewelry or other navel adornments. For instance, in some embodiments, navel retainer 100 a may include one or more central ornamentation mounting portions 118. A given central ornamentation mounting portion 118 may be provided, in part or in whole, at any one, or each, of brace portions 106, 108 and center portion 110. In some embodiments, navel retainer 100 a may include one or more peripheral ornamentation mounting portions 120. A given peripheral ornamentation mounting portion 120 may be provided, in part or in whole, at either, or both, of body portions 102, 104 or, more generally, body portion 101. In cases where a plurality of ornamentation mounting portions 118, 120 are provided, the arrangement (e.g., quantity, spacing, orientation, and so forth) thereof may be customized, as desired for a given target application or end-use. Moreover, the geometry and dimensions of a given ornamentation mounting portion 118, 120 may be customized, as desired.

A given ornamentation mounting portion 118, 120 may be of any suitable configuration that allows for a given manner of ornamentation to be mounted thereat in a temporary or permanent manner, as desired. The specific means by which a given ornamentation mounting portion 118, 120 may provide for mounting of ornamentation thereat may be customized, as desired for a given target application or end-use, and in at least some cases may be configured as typically done for mounting of jewelry and adornments. Some example suitable mounting means may include, for instance, snap, magnetic, clip, buckle, hook-and-loop, adhesive, bayonet-type, and threaded screw-type mounting elements, to name a few. Of course, as will be appreciated in light of this disclosure, navel retainer 100 a, 100 b additionally or alternatively may include one or more integrated ornamentations and is not intended to be limited only to attachable/detachable ornamentations. Other suitable configurations for ornamentation mounting portion(s) 118, 120 will depend on a given application and will be apparent in light of this disclosure.

Navel retainer 100 a, 100 b may be constructed from any of a wide range of materials, any of which optionally may be medical-grade. For example, in some embodiments, navel retainer 100 a, 100 b may be constructed, in part or in whole, from a metal or alloy, such as a stainless steel (e.g., a surgical stainless steel), gold, silver, or platinum, to name a few. In some embodiments, navel retainer 100 a, 100 b may be constructed, in part or in whole, from an elastomeric or polymeric material (e.g., such as a plastic, rubber, or silicone), a ceramic material, a composite material, a mineral material, a glass material, or a wooden material, among others. As will be appreciated in light of this disclosure, the selection of different construction materials may allow for navel retainer 100 a, 100 b to have sufficient rigidity and/or softness (e.g., flexibility) to achieve desired navel shape and size characteristics for a user. In some instances, body portion 101 may be a rigid body, whereas in some other instances, it may be a semi-rigid or flexible body. The dimensions D₁-D₈ (e.g., height, width, length, diameter, radius, thickness, etc.) of various portions of navel retainer 100 a, 100 b may be customized, as desired for a given target application or end-use. In addition, the coloration of a given portion of navel retainer 100 a, 100 b may be customized, as desired. Other suitable configurations for navel retainer 100 a, 100 b will depend on a given application and will be apparent in light of this disclosure.

In accordance with some embodiments, navel retainer 100 a, 100 b may be configured to be expandable and collapsible to adjust its size and/or geometry. In the fully collapsed state of navel retainer 100 a, 100 b, body portion 101 may be characterizable as having its minimum possible size (e.g., smallest possible diameter/width or other dimension). In the fully expanded state of navel retainer 100 a, 100 b, body portion 101 may be characterizable as having its maximum possible size (e.g., largest possible diameter/width or other dimension). In accordance with some embodiments, navel retainer 100 a, 100 b further may be configured with one or more partially expanded states in which body portion 101 may be characterizable as having an intermediate size somewhere between its minimum and maximum possible sizes. Also, as previously noted, in adjusting the size of body portion 101, the overall geometry of navel retainer 100 a, 100 b may change as well, at least in some cases.

In accordance with some embodiments, adjustment mechanism 112 may be configured to transition navel retainer 100 a between any of its various states, changing the size and/or geometry of body portion 101. As body portion 101 may interface, directly or indirectly, with tissue within the navel when navel retainer 100 a, 100 b is deployed therein, adjustment of the size and/or geometry of body portion 101 accordingly may alter the size and/or shape of the surrounding navel. In this manner, the native adjustability of navel retainer 100 a, 100 b may be utilized, in accordance with some embodiments, to adjust or maintain the size and/or shape of the host navel, for example, during a healing period or as otherwise desired.

FIGS. 5-6 illustrate several views of a navel retainer 100 c configured in accordance with another embodiment of the present disclosure. As can be seen, navel retainer 100 c may include a body portion 101 having a first end portion 102 a and an opposing second end portion 102 b and may be configured to interface, directly or indirectly, with the interior sidewalls of a navel. In some embodiments, such as that generally shown in FIG. 5, body portion 101 may be of single-piece construction (e.g., may constitute a monolithic element). In some other embodiments, however, body portion 101 may be of multi-piece construction (e.g., may constitute a polylithic element). Depending on the orientation of navel retainer 100 c when inserted within a navel, a given region of body portion 101 may be considered, for example, an upper body portion, lower body portion, or side body portion of navel retainer 100 c, as the case may be. In some embodiments, a given region of body portion 101 optionally may be configured to host one or more intervening layers (e.g., coatings, bumpers, guides, sleeves, coverings, guards, etc.) which are to be disposed between the tissue of the navel and body portion 101. The material selection and dimensions of such optional intervening layer(s) may be customized, as desired for a given target application or end-use.

In accordance with some embodiments, navel retainer 100 c may be configured such that its body portion 101 may compress and expand in size (and, optionally, change in geometry) along one or more axes. To that end, body portion 101 may be configured, in accordance with some embodiments, as a resilient element, characterizable as tending to recoil or spring back into shape despite being compressed or otherwise deflected from an undisturbed state. By virtue of its configuration, navel retainer 100 c may permit temporary reduction of the size of body portion 101 when acted upon by a compressive force of sufficient magnitude. In the weakening or absence of such a compressive force, a restorative force of body portion 101 may tend to expand the size of body portion 101. Thus, by virtue of its configuration, body portion 101 may provide navel retainer 100 c, in a general sense, with a spring-based adjustment mechanism. The degree of resilience may be customized by adjusting various characteristics of body portion 101, such as its material construction, geometry, and dimensions, for example.

Regarding material construction, navel retainer 100 c may be constructed from any of the various example materials discussed above, for instance, with respect to navel retainer 100 a, 100 b in accordance with some embodiments. As will be appreciated in light of this disclosure, the selection of different construction materials may allow for navel retainer 100 c to have sufficient resilience permitting flexibility for compression thereof yet also providing a sufficient restorative force causing body portion 101 to press against the tissue of a host navel to achieve desired navel shape and size characteristics for a user. In addition, the coloration of a given portion of navel retainer 100 c may be customized, as desired.

Regarding geometry, body portion 101 may be of generally rounded shape, in accordance with some embodiments. For instance, body portion 101 may be arcuate (e.g., semi-circular, semi-elliptical, open curve) or otherwise curved in shape and may have a substantially constant radius or a variable radius, as desired for a given target application or end-use. As can be seen from FIG. 1, for example, body portion 101 may be discontinuous, such that its end portions 102 a, 102 b are physically separated from one another by a gap 114.

As will be appreciated in light of this disclosure, the dimensions of gap 114 may change, for instance, depending on whether navel retainer 100 c is in its fully compressed state, fully expanded state, or some intermediate expanded state there between. In accordance with some embodiments, as body portion 101 is compressed or allowed to expand to effectuate adjustment of the size (and, optionally, geometry) of navel retainer 100 c, gap 114 may increase or decrease in size accordingly. As gap 114 approaches zero, end portions 102 a, 102 b may come to be adjacent one another and perhaps interface, directly or indirectly, with one another, at least in a temporary manner. In some cases, body portion 101 may be collapsed manually or with the use of a separate tool. The restorative force of body portion 101 may tend to bias end portions 102 a, 102 b away from one another, increasing the size of gap 114 and producing an overall increase in the size of body portion 101.

In some embodiments, navel retainer 100 c may be configured such that, in its fully compressed state, end portions 102 a, 102 b may interface (or otherwise be proximate one another) in a manner that results in body portion 101 being of generally circular geometry. In some other embodiments, navel retainer 100 c may be configured such that, in its fully compressed state, end portions 102 a, 102 b may interface (or otherwise be proximate one another) in a manner that results in body portion 101 being of generally elliptical, oval, oblate, prolate, or other curved geometry suitable to fit within a navel of a given size. In accordance with some embodiments, navel retainer 100 c may be configured such that, in its fully compressed state, its body portion 101 may be of a first geometry (e.g., a circular geometry), whereas in a partially or fully expanded state, its body portion 101 may be of a different second geometry (e.g., an elliptical geometry).

Regarding dimensions, the dimensions D₁-D₈ (e.g., height, width, length, diameter, radius, thickness, etc.) of various portions of navel retainer 100 c may be customized, as desired for a given target application or end-use. As will be appreciated in light of this disclosure, it may be desirable to ensure that the dimensions of a given region of body portion 101 are sufficiently large or small, as the case may be, to provide for a given target degree of resilience. Other suitable materials, geometries, and dimensions for body portion 101 will depend on a given application and will be apparent in light of this disclosure.

In accordance with some embodiments, navel retainer 100 c optionally may include one or more points of attachment for ornamentation, such as navel piercing jewelry or other navel adornments. For instance, in some embodiments, navel retainer 100 c may include one or more ornamentation mounting portions 118. In cases where a plurality of ornamentation mounting portions 118 are provided, the arrangement (e.g., quantity, spacing, orientation, and so forth) thereof may be customized, as desired for a given target application or end-use. Moreover, the geometry and dimensions of a given ornamentation mounting portion 118 may be customized, as desired.

A given ornamentation mounting portion 118 may be of any suitable configuration that allows for a given manner of ornamentation to be mounted thereat in a temporary or permanent manner, as desired. The specific means by which a given ornamentation mounting portion 118 may provide for mounting of ornamentation thereat may be customized, as desired for a given target application or end-use, and in at least some cases may be configured as typically done for mounting of jewelry and adornments. Some example suitable mounting means may include, for instance, snap, magnetic, clip, buckle, hook-and-loop, adhesive, bayonet-type, and threaded screw-type mounting elements, to name a few. Of course, as will be appreciated in light of this disclosure, navel retainer 100 c additionally or alternatively may include one or more integrated ornamentations and is not intended to be limited only to attachable/detachable ornamentations. Other suitable configurations for ornamentation mounting portion(s) 118 will depend on a given application and will be apparent in light of this disclosure.

In accordance with some embodiments, navel retainer 100 c may be configured to be expandable and compressible to adjust its size and/or geometry. In the fully compressed state of navel retainer 100 c, body portion 101 may be characterizable as having its minimum possible size (e.g., smallest possible diameter/width or other dimension). In the fully expanded state of navel retainer 100 c, body portion 101 may be characterizable as having its maximum possible size (e.g., largest possible diameter/width or other dimension). In accordance with some embodiments, navel retainer 100 c further may be configured with one or more partially expanded states in which body portion 101 may be characterizable as having an intermediate size somewhere between its minimum and maximum possible sizes. Also, as previously noted, in adjusting the size of body portion 101, the overall geometry of navel retainer 100 c may change as well, at least in some cases.

In accordance with some embodiments, the restorative force exerted by virtue of the configuration of body portion 101 may serve to transition navel retainer 100 c between any of its various states, changing the size and/or geometry of body portion 101. As body portion 101 may interface, directly or indirectly, with tissue within the navel when navel retainer 100 c is deployed therein, adjustment of the size and/or geometry of body portion 101 accordingly may alter the size and/or shape of the surrounding navel. In this manner, the native adjustability of navel retainer 100 c may be utilized, in accordance with some embodiments, to adjust or maintain the size and/or shape of the host navel, for example, during a healing period or as otherwise desired.

Methodologies

FIG. 7 is a flowchart illustrating a method 200 of using a navel retainer in accordance with an embodiment of the present disclosure. Method 200 may be utilized, in accordance with some embodiments, in combating contracture of a navel, for example, during a healing period. Method 200 may begin as in block 202 with inserting a navel retainer into a navel, wherein the navel retainer is of a first configuration. In an example case, the navel retainer may be, for instance, either navel retainer 100 a or 100 b, described herein. The first configuration may be characterized as being of a given first size and geometry. When inserted, the body portion of the navel retainer may interface, directly or indirectly, with the sidewall tissue (or other tissue) within the navel. The snugness of the fit achieved in such initial insertion may be of a greater or lesser degree, as the case may be, but may change with adjustment of the size and/or geometry of the navel retainer, as discussed further below.

Method 200 may continue as in block 204 with adjusting the navel retainer, optionally within the navel, to a second configuration of different size and/or geometry than the first configuration. In an example case, adjustment may be provided, for instance, via adjustment mechanism 112, described herein. In performing such adjustment, the body portion of the navel retainer may increase or decrease in size and, optionally, may change in geometry. In this manner, the snugness of the fit of the navel retainer may change, and the body portion may come to exert a greater or lesser pressure on tissue within the host navel than may be present during the initial insertion (block 202).

Method 200 optionally may continue as in block 206 with removing the navel retainer from the navel. In some cases, it may be desirable to adjust (e.g., reduce) the size of the navel retainer prior to attempting removal, though in at least some instances, no such adjustment may be needed to effectuate removal. Optionally, after removing the navel retainer, method 200 may return to block 202, the navel retainer being reinserted within the navel (e.g., such as may be performed after cleaning the navel retainer and/or checking on the condition of the navel during the healing process).

Method 200 optionally may continue as in block 208 with inserting a separate maintenance device within the navel. Thus, if the navel retainer of blocks 202-206 is configured as the navel retainer 100 a of FIGS. 1-2, then the separate maintenance device may be configured, in accordance with some embodiments, as the navel retainer 100 b of FIGS. 3-4. The maintenance device may be employed once the desired navel size and shape are obtained and may be used on a temporary or perpetual basis.

As will be appreciated in light of this disclosure, the amount of time that may be allowed to elapse between any of insertion (block 202), adjustment (block 204), optional removal (block 206), and optional insertion for maintenance (block 208) may be customized, as desired for a given target application or end-use. It should be noted that any of these various periods need not be strictly continuous, as the navel retainer or the separate maintenance device, as the case may be, may be removed temporarily or as otherwise desired, for instance, to permit cleaning or other upkeep or inspection of the host navel and such devices.

FIG. 8 is a flowchart illustrating a method 300 of using a navel retainer in accordance with another embodiment of the present disclosure. Method 300 may be utilized, in accordance with some embodiments, in combating contracture of a navel, for example, during a healing period. Method 300 may begin as in block 302 with inserting a navel retainer into a navel, wherein the navel retainer is of a first compressed configuration. In an example case, the navel retainer may be, for instance, navel retainer 100 c, described herein. The first configuration may be characterized as being of a given first size and geometry. When inserted, the body portion of the navel retainer may interface, directly or indirectly, with the sidewall tissue (or other tissue) within the navel. The snugness of the fit achieved in such initial insertion may be of a greater or lesser degree, as the case may be, but may change with adjustment of the size and/or geometry of the navel retainer, as discussed further below.

Method 300 may continue as in block 304 with allowing the navel retainer to expand, optionally within the navel, to a second expanded configuration of different size and/or geometry than the first compressed configuration. In an example case, expansion may result from the resilience of body portion 101, described herein. In allowing such adjustment, the body portion of the navel retainer may increase in size and, optionally, may change in geometry. In this manner, the snugness of the fit of the navel retainer may change, and the body portion may come to exert a greater or lesser pressure on tissue within the host navel than may be present during the initial insertion (block 302).

Method 200 optionally may continue as in block 306 with removing the navel retainer from the navel. In some cases, it may be desirable to compress (e.g., reduce) the size of the navel retainer prior to attempting removal, though in at least some instances, no such adjustment may be needed to effectuate removal. Optionally, after removing the navel retainer, method 300 may return to block 302, the navel retainer being reinserted within the navel (e.g., such as may be performed after cleaning the navel retainer and/or checking on the condition of the navel during the healing process).

Method 300 optionally may continue as in block 308 with inserting a separate maintenance device within the navel. The maintenance device may be employed once the desired navel size and shape are obtained and may be used on a temporary or perpetual basis.

As will be appreciated in light of this disclosure, the amount of time that may be allowed to elapse between any of insertion (block 302), expansion (block 304), optional removal (block 306), and optional insertion for maintenance (block 308) may be customized, as desired for a given target application or end-use. It should be noted that any of these various periods need not be strictly continuous, as the navel retainer or the separate maintenance device, as the case may be, may be removed temporarily or as otherwise desired, for instance, to permit cleaning or other upkeep or inspection of the host navel and such devices.
